Abstract
The utility model relates to an intelligent optimization control system for aeration rate in a process of sewage processing, which comprises an aerator, an aerator controller, a PLC system, an upper computer monitor system, and a sewage aeration intelligent optimization controller. A detecting instrument transmits analog quantity information of original water flow capacity A1 and dissolved oxygen concentration to the PLC system by a hardwiring manner or network communication. The PLC system calculates aeration rate according to set value of dissolved oxygen concentration and transmits output analog quantity signals of aeration rate A2 to the aerator through the aerator controller. The PLC system performs data communication with the upper computer monitor system, and the upper computer monitor system performs data communication with the aeration rate intelligent optimization controller. The intelligent optimization control system model can accurately control aeration flow rate by utilizing blower aeration rate intelligent control, enable the dissolved oxygen concentration in each aeration tank to meet sewage drainage standard, and enable effluent to meet sewage discharge standard, thereby reducing power consumption of the blower and saving operating cost.
Description
Technical field
The utility model relates to a kind of sewage aeration intelligent optimizing control system, is two or more parallel bio-aeration pools especially for present most of sewage treatment plants aeration system, realizes online accurate control aeration rate.
Background technology
In present control technology, most of sewage treatment plants adopt two simple single loop controls that dissolved oxygen concentration is regulated.The one, adopt dissolved oxygen concentration detector and fan blower as simple control loop.When dissolved oxygen concentration during greater than setting value, turn blower frequency down; When dissolved oxygen DO solubility is excessive, transfer big dissolved oxygen concentration.The 2nd, adopt dissolved oxygen concentration detector and gas flow regulating valve as control loop.When imbalance appearred in two or more parallel bio-aeration pool dissolved oxygen concentrations, general employing was controlled manually or is adopted simple expert control system that dissolved oxygen concentration is controlled.Above-mentioned control method shortcoming is: have the phenomenon of control action coupling in the control of the gas flow valve of a plurality of aeration tanks and the control of blower frequency, can accurately not control dissolved oxygen concentration.
The utility model generally is made up of two or more parallel bio-aeration pools at the most of sewage treatment plants of present China aeration system, the present situation that activated sludge process wastewater treatment automatization level falls behind is relatively explored feasibility and the validity of using Intelligent Control Strategy.Because the water quality instability of native sewage water in the sewage disposal process, external environmental interference is serious, mainly be to utilize the vital movement of microorganism to remove organism on the water purification means, the factor that influences wastewater treatment efficiency is a lot, therefore, the accurate model of setting up the sewage process is very difficult, and based on the various control methods of mathematical models the control of sewage disposal process is also just seemed and to be difficult to obtain desirable effect more.So adopt advanced optimal control method, the control dissolved oxygen concentration had very important meaning.
The utility model content
The purpose of this utility model provides a kind of aeration in sewage treatment amount intelligent optimizing control system, can realize the aeration flow is accurately controlled, make each aeration tank dissolved oxygen concentration reach target call, water outlet reaches set sewage drainage standard, thereby reduces fan blower power consumption, saving operation cost.
For achieving the above object, technology contents of the present utility model is described below:
A kind of aeration in sewage treatment amount intelligent optimizing control system, it is characterized in that, comprise aerator, aeration controller, PLC system, ipc monitor system, sewage aeration intelligent optimization controller, measuring instrument imports the analog quantity information data message of raw water flow A1, the dissolved oxygen concentration A3 of detection into the PLC system by hardwire mode or network communication mode, the PLC system calculates aeration rate according to the dissolved oxygen concentration setting value, gives aerator by aeration controller with aeration rate A2 output analog signals; Described PLC system and ipc monitor system, ipc monitor system and sewage aeration intelligent optimization controller carry out data communication.
Compared with prior art, the beneficial effects of the utility model are:
Adopt fan blower aeration rate Based Intelligent Control, can accurately control the aeration flow, make each aeration tank dissolved oxygen concentration reach target call, water outlet reaches set sewage drainage standard, thereby reduces fan blower power consumption, saving operation cost.
Description of drawings
Fig. 1 is the structural drawing that the utility model method adopts the aeration control system.
Embodiment
The technical solution adopted in the utility model is On-line Control aeration flow: each aeration tank dissolved oxygen concentration and the dissolved oxygen concentration setting value that the dissolved oxygen sensing instrument are collected detection are released one group of dissolved oxygen concentration eigenwert through expert knowledge library, and this dissolved oxygen concentration eigenwert is passed through fuzzy controller calculate, calculate best fan blower aeration rate, accurately regulate blower frequency, aeration rate is effectively distributed.
In Fig. 1, mainly formed by three-decker: technology controlling and process layer L0, basic automatization layer L1 and process control station L2.Formed by process equipment aerator (fan blower and gas flow regulating valve), aeration tank, second pond at the L0 layer.The information data of transmitting has the A1(raw water flow), A2(fan blower aeration rate), the A3(dissolved oxygen concentration), the information between A4(PLC and the host computer), the information between A5(host computer and the control of sewage aeration intelligent optimization) measuring instrument will detect information A 1, A3 and PLC system transmission analog quantity information data by hardwire mode or network communication mode, PLC calculates aeration rate according to the dissolved oxygen concentration setting value and exports analog quantity output signals A2 to fan blower and gas flow regulating valve.
Formed by PLC control system L1_1, the aeration controller PLC L1_2 of system and the L1_3 of ipc monitor system at basic automatization layer L1.In L1_1, detection variable information data A3 is carried out filtering and handle, and according to handling back A3 data message, select aeration controller output A2 controlled quentity controlled variable at L1_2.And realize significant data demonstration, real time data demonstration, warning and accounting logging at L1_3, and by communication modes and L1_1, L1_2 and L2_3(Process Control System computing machine) carry out the data transmission.The expert's decoupling zero control, the gas flow regulating valve Fuzzy Decoupling Control that comprise sewage aeration intelligent optimization control module L2_1(fan blower aeration rate expert fuzzy intelligence control system, blower frequency control and flow control valve in the L2 layer).L2 finishes important parameter adjustment and critical functions such as typing (as retardation time), expert data backup.
